A localization method measuring two-way range is efficient for a rover especially on small planetary bodies, where conventional methods of localization could not apply to. Numerical simulations have shown that the method can localize a rover with the accuracy of several meters, assuming small body, whose diameter is less than 1 [km]. Rotational parameters of an investigating planetary body have been assumed to be known, however, these parameters are also estimated amount that they may include some uncertainties in actual. This paper describes influence analysis on localization accuracy of uncertainties in rotational parameters and proposes a method, which estimates both position of a rover and rotational parameters.
